Miantenoma is a privately owned irrigation dam located in the Weld County of Colorado, specifically in the city of Gilcrest. Built in 1895, this earth dam stands at a height of 22 feet and spans a length of 570 feet. With a storage capacity of 219 acre-feet, Miantenoma serves the primary purpose of irrigation, drawing water from the Howlett Gulch river or stream.

Despite being regulated by the Colorado Department of Water Resources and inspected regularly, Miantenoma has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in August 2015. The dam has a moderate risk rating of 3, suggesting the presence of some potential risks that may require management measures in the future. With a spillway width of 10 feet and a maximum discharge rate of 250 cubic feet per second, Miantenoma is equipped to handle controlled releases of water to prevent overflow during heavy rainfall or flooding events.

For water resource and climate enthusiasts, Miantenoma presents an interesting case study of a historic irrigation dam that continues to play a crucial role in the water management practices of the region. Its location in the picturesque surroundings of Weld County, Colorado adds to its appeal as a point of interest for those interested in the intersection of water infrastructure and environmental conservation. As efforts to address climate change and water scarcity intensify, understanding the management and maintenance of structures like Miantenoma will be key in ensuring the sustainable use of water resources for future generations.
